The federal police issued arrest warrants for Khaled Sharrouf and Mohamed Elomar, two Sydney residents who are now fighting with the Islamic State in Iraq and have threatened to kill Australian soldiers as well as all non-Muslims. Authorities estimate that 150 Australians are currently fighting in Syria and Iraq, and that about 60 of them have joined extremist groups. Attorney General George Brandis said Islamic extremism is germinating “within the suburbs of Sydney and Melbourne and Brisbane.”
